I’ve searched high and low for a good native Linux Twitter client, but there’s nothing out there that can really compete with TweetDeck. At least not in terms of functionality. TweetDeck is based on Adobe’s AIR platform and as a result is quite heavy on resources. But the biggest problem I had with it was getting it to open links in my default browser. It disregarded my setting and used Firefox to open all links. Twitter is far less fun if you need to carefully copy paste every link to a new tab in your browser. As it turns out, the issue is with AIR, not just TweetDeck, and it took quite a while and a lot of help for me to find a working solution.More Getting Adobe AIR to use the default browser under Ubuntu
